Physics Special Colloquium, November 8, 2004QCD amplitudes and string theoryAnastasia VolovichKavli Institute for Theoretical PhysicsThe number of Feynman diagrams which contribute to an n-particle scattering amplitude in quantum chromodynamics grows faster than factorially with the number n, making it hard to compute the amplitudes explicitly. The construction of more efficient computational methods which also expose otherwise hidden rich mathematical structure has benefited substantially from string theory input. In addition, string theory dualities offer a promising strategy for solving strongly-coupled gauge theories such as QCD. I will review the most recent progress in these directions. 10:30 a.m., Smith Laboratory, Room 1094Refreshments served in Smith 1094 at 10:00 a.m. |
